How to distinguish driver quality of roadway lighting？
First , check if the roadway lighting driver is energy saving and efficient.
The roadway lighting project is the representative project . In the light-emitting components, the LED chips have achieved very good energy saving effects, but the energy saving of LED roadway lighting has been ignored by many manufacturers, so there is no doubt that driver will be the most important component in the future.
Second , look at the lightning protection performance of the roadway lighting driver.
Roadway lighting are installed outdoors. Lightning strike is a very big threat. Therefore, roadway lighting need to have strong lightning protection. Connecting leads and grounding networks to roadway lighting , can protect road lighting fires , personal injury and lightning strikes from causing safety accidents. The internal lightning protection system refers to the internal protect roadway lighting through grounding, voltage protection, etc. Therefore, it is necessary to distinguish the quality of roadway lighting for drivers. Lightning protection is one of the requirements.
Third , look at the design margin of the LED roadway lighting driver.
At present, the application of led roadway lighting is very complicated. The main reason is that the driver voltage is unstable. The actual input voltage often are deviation and unsafe , such as wave impact , always affect operation of roadway lighting driver , so that driver requires margin.
Fourth , check if the LED roadway lighting driver uses high-quality components.
LED roadway lighting drivers are mainly used in outdoor environments. They have to withstand the harsh environment of wind, rain, and thunder and lightning for many years. The highest temperature outdoors can reach 50 ° C, and the lowest temperature can reach -40 ° C. At present, the key components of the drivers are still some passive components and power components, such as capacitors, inductors, MOS, etc., Generally speaking, the drivers stability of famous brands are better.
